Ask a question

A. Dear Crystal

Thanks for the email.

Do you know if your parent (the one who is the child of the affected grandparent) shows any signs of HD or has had a test? This would be pretty important information when trying to work out the risk to you or your child.

If you don’t know that information then your risk of carrying the gene is 25% and your son’s risk is around 12%.

Your son’s condition does not sound very like Huntington disease and a bit more like a tic disorder.

I hope that is helpful

Best wishes

Hugh Rickards
